Primary finding
Probable cause
The pilot’s failure to see the taxiway when returning to the ramp from the snow-covered runway, which resulted in the airplane rolling down an embankment.
Investigator assessment
Analysis narrative
The pilot reported that, while taxiing onto the snow-covered runway for departure, he was unable to see the runway markings. He added that he decided to cancel the flight and return to the ramp, but the airplane exited the runway and went down an embankment. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
